Apple could but Apple would rather die they allow something to work cross platform.
I think they are also absolutely addicted to cruddy pay to win mobile games and they don’t want to give up that sweet drip feed of IAP that they get a 30% cut of… which is substantial.
For funsies, try searching App Store apps and find a way to filter out results for apps with IAP. Nope!
(Source: me, who spent time at a mobile gaming company as we figured out how to continuously optimize our funnels so that some rich dudes in Qatar could continue to spend $40K a month on useless cosmetics.)
I think that filter is called Apple Arcade but of course it's not free.
